What Action is the EPA Taking?

US Environmental Protection Agency - Restrictions in products

The Frank R. Lautenberg Chemical Safety for the 21st Century Act has initiated the US Toxic Substances Control Act (TSCA) reform

 

According to this reform, the federal Environmental Protection Agency (EPA) must take action on particular chemical substances identified as persistent, bioaccumulative, and toxic (PBT). 

 

As a result, after thorough Federal TSCA Work Plan for Chemical Assessments, the EPA has decided to restrict the use of the following five substances in products:

TSCA : 5 restricted substances in Products
  • PIP (3:1), or Phenol, Isopropylated Phosphate (3:1);
  • DecaBDE, or Decabromodiphenyl Ether. DecaBDE is also one of the PBDEs restricted under RoHS;
  • PCTP, or Pentachlorothiophenol;
  • 2,4,6-TTBP, or 2,4,6-tris(tert-butyl)phenol;
  • HCBD, or Hexachlorobutadiene. The EU Persistent Organic Pollutants (POP) regulation also rules HCBD.
